TAS5630DKD

Overview

The TAS5630DKD is a stereo Class-D and Class-G audio amplifier manufactured by Texas Instruments. It delivers up to 300 W of output power into an 8-ohm load at 42 V, or 600 W into a 4-ohm load at 52.5 V. The device operates with a supply voltage range from 25 V to 52.5 V and features a total harmonic distortion plus noise (THD+N) of 0.03%. It utilizes a 44-pin HSSOP package and supports differential or single-ended inputs with a fixed gain of 23 dB.

Feature Summary

• Integrates Class-D and Class-G topologies for high efficiency and low heat dissipation in high-power applications.
• Features integrated feedback loops to simplify system design and reduce external component count.
• Supports both differential and single-ended analog input configurations for flexible interfacing.

Applications

• High-fidelity home theater systems
• Professional audio amplification equipment
• Active loudspeaker designs

Procurement Notes

Verify the current lifecycle status as the component may be discontinued or not recommended for new designs. Confirm package availability and lead times through authorized distributors. Ensure compliance with RoHS directives and moisture sensitivity levels during storage and handling procedures.

Selection Notes

Select this part for applications requiring high output power with minimal thermal management complexity. Consider the 44-pin HSSOP package constraints for PCB layout. Verify that the target load impedance matches the specified power ratings to ensure optimal performance and reliability.

Part Context
